A new technology platform is presented that utilized capacitive micromachined ultrasonic transducers (CMUT) for the on-chip integration of proximity and tactile sensing. This platform integrated in robotic grippers enables tactile and reactive grasping. A single channel proximity system is demonstrated to distinguish objects and reveal high spatial resolution to distances of 10 mm.

The magneto-impedance of NiFe/Al/NiFe lines intended to form a protection against physical attacks was studied. Their behavior when exposed to the magnetic field generated by a DC current flowing through them, as well as their sensitivity to tiny modifications of their geometry are reported. Their integration inside the packaging of a system is presented as an opportunity to protect multiple vulnerable dies collectively to make a secure system.

High-level models serve their purpose for a time- and memory-efficient abstraction of the implementation and functionality of integrated circuits, but often experience high distinction between the transistor-level simulation and measurements. A 12-bit SAR ADC is designed as a high-level model as well as a transistor-level implementation in a 0.18 μm technology for smart sensor system applications. An accurate high-level model is developed and compared to actual transistor-level simulations as well as measurement results of the manufactured chip. Crucial design steps are shown to accurately design the high-level model and achieve a model that closely follows the behavior of the manufactured circuit, which can be used to highly accelerate the design process of smart sensor systems

The Joint International Master in Smart Systems Integrated Solutions (SSIs) will graduate candidates for the ever-growing industry of Smart Systems, ubiquitous in all sectors of society including healthcare, transport, environment protection, energy and security. SSIs is given jointly by three universities in three European countries: Aalto University (Helsinki, Finland), University of South-Eastern Norway (USN), and Budapest University of Technology and Economics (BME) (Hungary), utilizing the complementary expertise and laboratory facilities of the three partners to create a unique programme with a more holistic approach than a single university could give. The programme collaborates closely with industry, and has EPoSS as Associated Partner, assuring its relevance. SSIs builds on the Joint International Master in Smart Systems Integration (SSI), which has been running since 2013 with Heriot-Watt University (Edinburgh, Scotland) co-ordinating a consortium with USN and BME.SSIs students benefit from the combined expertise of the consortium, as well as from the extended socio-cultural knowledge obtained by living in three different European countries that represent distinctively different aspects of the diverse Europe. The students in the programme show excellent performance, and the employability of graduates has proven to be very high.

According to the UNESCO World Water Development Report 2019 [1], one half of all people with insufficient access to drinking water are located in African states. In the sub-Saharan region the percentage of those with access to clean drinking water is at 24% only. The exploitation of new water sources by means of laboratory water quality analysis may lead to costs of about 30$ each [2]. In view of the above, a low-cost sensor system has been developed that intends to provide a feedback on the general quality of a water probe and gives a statement on the possibility of dissolved chemicals in the probe.

This paper reports on design, technology and mechanical characterization in air of a piezoelectric aluminum nitride (AlN) based micromachined ultrasonic transducer (PMUT) with six radial symmetric arrays. The PMUT consists of 4018 single membranes with a resonance frequency of 3.4 MHz, a quasi-static deflection of 272 pm/V and a resonant deflection of up to 71.3 nm/V. The small standard deviation of the resonance frequency over the chip is 47 kHz.

In this paper, we demonstrate a multi-membranes piezoelectric micromachined ultrasonic transducer (pMUT) device devoted to air-borne pulse-echo measurement with an angular resolution of 18 degrees. The setup includes a one-dimensional pMUT array of 5 bimorph AlN-based membranes working at 113.6 kHz for reception and a single pMUT membrane for emission. Pulse-echo measurement are achieved on an acoustic target located at 40 cm from the device. A beamforming strategy is implemented to achieve spatial filtering of the signal. The angle of the acoustic beam is manually defined and clearly evidenced by signal processing, confirming experimentally the potential of pMUT device for air-borne beamforming-based system.

Colloidal quantum dots (QDs) have attracted significant interest because of their unique properties, such as high quantum efficiency, size-dependent emission wavelength, high color purity and low-cost solution processability. These properties make them one of the most promising emission materials for thin film light emitting diodes (LEDs) of the future. Although QD-LEDs have been in the focus of science for quite some time, many topics are still neglected, such as the dynamics, which expresses the switching speed for these LEDs. However, this knowledge could be crucial for the application of such LEDs in communication or sensor technology. This work will give an overview of the influence of the size of the QDs used and the associated emission wavelength. The particles used have cores of cadmium selenide (CdSe) of different sizes and are covered by shells of zinc sulfide (ZnS). The examined LEDs are constructed in the same way and differ only in the QDs used as emission layer. The dynamics of these samples were investigated by electro-optical measurements like Modulated Electroluminescence Spectroscopy (MELS) and Transient Electroluminescence Measurements (TEL). This work will show that the dynamics of LEDs increase with the core size of the QDs used. We assume that these results will mark the progress in the development and realization of faster QD LEDs.

Recently automated frameworks have been proposed, mapping neural networks from a high-level description onto embedded devices, most of them in an end-to-end manner. This paper aims to give an overview of their main characteristics and achievements. A special focus is lying on internal predictions during design space exploration (DSE) regarding hardware targets (performance, area or power consumption), enabling fast exploration of the individually defined search spaces, especially in early design stages. Additionally, recent research results that are not part of such frameworks, but present novel estimation techniques are also covered by this work.

The development of a compact, battery-powered sensor platform intended for underwater applications and using hydroacoustic communication is reported. The design and manufacturing of the device is described with emphasis on the method used to monitor and reduce the current consumption. The devices have been encapsulated in epoxy and evaluated under field conditions, which showed that the system is usable in its current form. In addition to hardware improvements, e.g., in order to increase battery lifetime, the next generation of the system will implement forward error correction and improved receiver signal processing to reduce the impact of signal reflections.
